LANTERN.

SPECIFICATION forming part of Letters Patent No. 278,920, dated June 5, 1883. Application filed February 10, 1883. (No model.)

To all whom it may concern Be it known that I, JoHXj H. EWING, of IVheeling, in the county of Ohio and State of \Vest Virginia, have invented certain new and useful Improvements in Lanterns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to an improvement in tubular lanterns, and is threefold in its nature, comprehending the provision of a lantern of the character designated, with improved means for supporting the top of the globe, with an improved arrangement of deflectors for the upper and lower ends of the lantern-tubes, and with an improved disk for supporting the bottom of the globe, the body of said disk being provided with an aperture through which the lantern is lighted.

Vith these objects in view my invention consists in certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

. locking-collar.

In the accompanying drawings, Figure 1 is a view in perspective of a lantern embodying my invention. Fig. 2 is a view thereof in vertical section. Fig. 3 is a detached view of the reflector. Fig. l is a detached view of the Fig. 5 is a plan view of the blank from which the same is made. Fig. 6 is a view in side elevation of the upper end of one of the airtubes, showing the deflectors associated therewith. Fig. '7 is a view, partly in front elevation and partly in section, of the devices shown in Fig. 6. Fig. 8 is a detached view, in vertical section, of the globe-supporting disk, showing the aperture therein and the hinged plate which covers it.

The reflector A, which ,is oval in general contour, is provided with a central aperture, B, in which the locking-collar G is mounted, the lower edge of the said collar being provided with two corresponding serrated inclinations, D, the same being isolated from each other by vertical slots E.

A gl0be-collar, F, fitting snugly within and extending above and below the collar C, is surmounted by a cap, G, the lower end of the collar being adapted to fit over the top of the lanternglobe H, pins I projecting from the periphery of the collar, and located near its lower edge, and arranged to respectively engage with the inclinations of the collar 0, and thus lock the globe-collar in its normal position of en- 5 5 gagement with the lantern-globe. To remove the globe, collar F is turned to register the pins I with the slots E. This done, the collar is lifted andthe globe removed. To secure the globe in place, the collar F is depressed and turned to engage the pins I wit-h the serrated inclinations D.

The abovedescribed arrangement for supporting the top' of the globe is not only simple in construction and in operation, but it is also very effective in use, inasmuch as after the pins I are engaged with the serrations of the inclinations any ordinary jarring to which the lantern may be subjected will not work them loose. This improved fastening also compen 7o sates, within certain limits, for variations in the heights of the globes.

Apertures -K, having radial extensions L, and formed in the reflector A, are adapted to receive the leaves of the four-leaved deflectors M, respectively surmounted by caps N, and extending above and below the reflector, their lower ends terminating just above the tops of the tubes 0.

Collars I, suspended from the lower face of the reflector are arranged to inclose both the upper ends of the tubes and the lower ends of the leaves of the deflectors These collars break the force of side currents, which they deflect over their upper and lower edges, and in this capacity they prevent the disturbance of the-currents descending from above and the formation of a vacuum at themouths of the tubes, and the withdrawal of the air from the burner, which would result therefrom. o

Deflecting-wings Q, extending from the collars P, aforesaid, to contiguous portions of the depending flange R of the reflector, are designed to converge air-currents onto the collars when the lantern is swinging endwise. Additionalprovision for supplying air to the tubes under the same circumstances is made in the perforations S, formed in the arms T, which unite the flange R and the tubes and support the latter.

By virtue of the within-described arrange ment of deflectors, air is supplied through the tubes to the burner U in abundant quantities. Nor is this supply interfered with by swinging the lantern in any direction, nor by suddenly raising or lowering it. The lower ends of the tubes intersect in an annular chamber, V, through which the collar \V, in which the burner U is inserted, centrally rises. The flame-chamber X, which is closed by the cone Y, and in which the burner is located, is separated from the chamber V by a perforated annulus, Z, which insures an even distribution of air throughout the flame-chamber.

The globe-supporting disk J, which is centrally perforated to fit over the burnencone, is provided with an upturned flange, A, which retains the globe in position. The said disk is provided with perforations B, designed to admit air into the interior of the globe, and also an aperture, C, the same being sufliciently large to permit the introduction of a match or other taper for lighting the lantern. The aperture also provides easy access to the flame for the purpose of extinguishing it. A

' plate, D, hinged to the upper face andnear the outer edge of the disk, is arranged to cover the said aperture. A handle, E, secured to the under face of the plate and extending outwardly therefrom, enables it to be readily raised to expose the aperture.

It is apparent that the different featuresof novelty herein set forth need not necessarily be associated in one lantern, but that they may be employed separately or in any combination desired. I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but that I hold myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what- I claim as new, and desire to secure by Letters Patent, is

1. 111 a tubular lantern, the combination, with a reflector, of a locking-collar mounted therein, its lower edge being provided with two serrated inclinations isolated from each other by vertical slots, and a globe-collar fitted in the loekingcollar, and provided with pins arranged .to engage with the serrated inclinations thereof, and to be lifted into the slots isolating said inclinations, substantially as set forth.

2. The combination, with the reflector and tubes of a tubular lantern, of four-leaved deflectors'surmounted by caps, said deflectors being located in apertures in the reflector and extending above and below it, their lower ends terminating just aboy'e the upper ends of the tubes, substantially'as set forth.

The combination, with the reflector and tubes of a tubular lantern, of deflectors located in apertures in the reflector, their lower ends terminating just above the upper ends of the tubes, and deflecting-collars inclosing the lower ends of the deflectors and the upper ends of the tubes, substantially as set forth.

4. The combination, with the reflector and tubes of a tubular lantern, of deflectors 1ocated in. apertures in the reflector, their lower ends terminating just above the upper ends of the tubes, deflectingcollars inclosing the lower ends of the deflectors and the upper ends of the tubes, and wings associated with the collars and arranged to converge air-currents thereupon, substantially as set forth.

The combination, with the reflector and tubes of a tubular lantern, of deflectors located in apertures in the reflector and terminating just above the upper ends of the tubes, dcflecting-eollars inclosing-the lower ends of the deflectors and the upper ends of the tubes, and perforated wings uniting the ends of the reflector and the tubes, the latter being thereby supported, substantially as set forth.

6. The combination, with the tubes of a tubular lantern, of an annular air-chamber, in which their lower ends intersect a collar rising centrally in said chamber, a burner mounted in the collar, a cone covering the burner, and a perforated annulus located in the said air-chamber and situated between the tubes and the burner, substantially as set forth.

7. The combination, with a globe-supporting disk provided with an aperture, of aplate hinged to the upper face and near the outer edge of the disk, and arranged to clear the ap crture therein, and a handle depending from the under face of the plate and extending outwardly therefrom, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
